That's an interesting question. Does temperature have an effect on the dielectric that changes the VOP? I'll have to try your experiment. Is that worth ten extra credit points? :-)
The copper in the coax has a positive temperature coefficient, which will contribute to an increased impedance (assuming the reactive components don't change). But, does the impedance have any effect on VOP? A quick Google search didn't find any information on this. AFAIK VOP is due to the dielectric properties.
